What will give the best results for flat stomach if I have a roll below my ribs and another below my belly button? (Photos)

I’m considering CoolSculpting, I had it done once, but I gained 5 pounds and my results went away. Or possibly liposuction, or BBL, or just weight loss. What do the doctors think is best? Even when I lose 20 pounds, I still have the same fat deposits, just smaller. The one below my ribs is most troubling, because it developed more recently. I’ve always had the roll below my belly button. I’m 5’8”, 36 years old and 155 pounds.
